That new midseason game show hosted by Joe Rogan and produced by Ashton Kutcher, Game Show in My Head, debuts Saturday on CBS. Before I saw the clip, I thought, well, it's a combination of their past shows Fear Factor and Punk'd. Not a bad guess. Turns out the show is much more like those taped bits David Letterman would do with neighboring deli owner Rupert Gee, sending Gee out into reality and ordering him to do and say things via hidden microphone. Here's a clip from the debut episode. For more clips, you can go here.
